DETAILED DESCRIPTION OF EMBODIMENTS

The present application is further described in detail by means of embodiments as follows, but it should be indicated that the scope of protection of the present application is not limited thereto.

Example 1

As shown in FIG. 4 to FIG. 11, a replaceable automobile interior rearview mirror support includes a support base 1, an OEM base 2, a base fixing block 21, and a replaceable support 3. The support base 1 is arranged in a body 6 of the automobile interior rearview mirror, the OEM base 2 is arranged on an automobile windshield 7, the base fixing block 21 is arranged below the OEM base 2, and the replaceable support 3 is arranged between the support base 1 and the OEM base 2. The replaceable support 3 includes a ball head base 31, a support pipe 32, a ball pad 33, a spring 34, and a conversion head 35. The ball head base 31 is fixed with the OEM base 2. The support base 1 is provided with a connector 4. The connector 4 is connected with the conversion head 35 on the replaceable support. A fastening screw 5 passes through the ball head base 31, the support pipe 32, the ball pad 33, the spring 34, and the conversion head 35 of the replaceable support 3 to lock and fix the connector 4. The connector 4 is provided with a screw hole 41 in a central portion thereof, a fixing column 42 matched with the support base 1 at a bottom, and inner bevel chamfers 43 at two sides, forming a round groove, at a top. The conversion head 35 is provided with a through hole 351 in a central portion thereof, outer bevel chamfers 352 at two sides, corresponding to the inner bevel chamfers 43 of the connector 4, at one end of the conversion head 35 which is connected with the connector 4, and a conversion ball head 353 at the other end of the conversion head 35.

The present example is directed to replacement of an OEM double-ball-head support. As shown in FIG. 1, since an OEM single-ball-head support is assembled in a support base of an automobile interior rearview mirror, and since the support base is installed with a rigid iron ring, it is hard to take out and replace the single-ball-head support. In order to solve this problem, some manufacturers make a separate design for the single-ball-head support to achieve replacement. However, no good solution is available in the market for replacing the double-ball-head support. This problem is solved in the present application by designing a connector in the rearview mirror and a conversion head of the replaceable support. In assembly, the connector 4 in the rearview mirror is firstly locked with the support base 1 in the rearview mirror using a bolt, the conversion head 35 is then aligned with the connector 4 in the rearview mirror, and the fastening screw 5 is finally made to pass through the ball pad 33 and the spring 34 in the support pipe 32, thereby locking the connector 4 in the rearview mirror. Thus, the whole double-ball support and the automobile interior rearview mirror form one integrated product. If replacement is needed, it only needs to unscrew the fastening screw to replace it by another double-ball support.

Example 2

As shown in FIG. 8 and FIG. 12 to FIG. 18, a replaceable automobile interior rearview mirror support comprises a support base 1, an OEM base 2, and a replaceable support 3. The support base 1 is arranged in an automobile interior rearview mirror, the OEM base 2 is arranged on an automobile windshield 7, and the replaceable support 3 is arranged between the support base 1 and the OEM base 2. The replaceable support 3 includes a ball head base 31, a support pipe 32, a ball pad 33, a spring 34, and a conversion head 35. The ball head base 31 is fixed with the OEM base 2. The support base 1 is provided with a connector 4. The connector 4 is connected with the conversion head 35 on the replaceable support. A fastening screw 5 passes through the ball head base 31, the support pipe 32, the ball pad 33, the spring 34, and the conversion head 35 of the replaceable support 3 to lock and fix the connector 4. The connector 4 is provided with a screw hole 41 in a central portion thereof, a connecting ball head 44 matched with the support base 1 at a bottom, and inner bevel chamfers 43 at two sides, forming a round groove, at a top. The conversion head 35 is provided with a through hole 351 in a central portion thereof, outer bevel chamfers 352 at two sides, corresponding to the inner bevel chamfers 43 of the connector 4, at one end of the conversion head 35 connected with the connector 4, and a conversion ball head 353 at the other end of the conversion head.

The present example is directed to replacement of a three-ball-head support. The connecting ball head 44 arranged in the rearview mirror of this example is located at the bottom of the connector 4. Since a conventional three-ball-head support includes a ball head located at a connecting portion between the three-ball-head support and the automobile interior rearview mirror, one end of the double-ball head is connected with the support base, and the other end thereof is connected with the three-ball head support. Due to the tight squeeze of the support base, it is very hard to manually replace the support easily. The present application makes a separate design, that is, the three-ball head support is modified to include two portions, one portion being the connector 4 in the rearview mirror, and the other portion being the conversion head 35. In assembly, the connector 4 in the rearview mirror is firstly pressed into the support base 1 of the automobile interior rearview mirror using a fixture. If the three-ball-head support needs to be replaced, a replaceable support 3 with a double ball head is firstly connected with the connector 4 inside the rearview mirror, then a fastening screw is made to pass through the ball pad 33 and the spring 34 in the support pipe 32, then the replaceable support 3 having the conversion head 35 is secured with the connector 4 in the rearview mirror, and after secured, the ball head base 31 is assembled with the OEM base 2, thereby finishing the replacement of the three-ball-head support. In order to improve strength of the whole combined support, the replaceable support 3 in the present application is manufactured by a zinc alloy die-casting process, which makes the replaceable support not only environment-friendly and rigid, but also of certain strength. The OEM base 2 is equipped to the original automobile, and the replaceable support 3 which has the conversion head 35 is fixed, through the fastening screw, with the connector 4 which is placed in the automobile inner rearview mirror.

Besides, rearview mirror supports in the prior art are not practical enough and easily cause shaking of the rearview mirror, which the inventor found after long-term research is due to unreasonable structure design. An automobile interior rearview mirror support common in the market is as shown in FIG. 19. In such rearview mirror support, a bolt is used to connect a support in a middle portion, a ball head and a support arm are integrated, and a wire support passes through the ball head on the support arm. A support ball inside the existing rearview mirror extends outwardly too much, such that a wire can pass through the support ball to extend out, however the total length of the rearview mirror support is greatly increased, which makes it hard to install the rearview mirror support to some types of automobiles perfectly. Moreover, many types of automobiles, if the rearview mirror support is to be mounted complying with safety standard requirements, would have the whole rearview mirror support very long, which is quite unpleasing. A too long support further makes the rearview mirror easy to shake.

Given this, in order to improve this situation, the inventor of the present application, who has made some improvements on the rearview mirror supports, invented a rearview mirror support having a screw for locking at a front face and a wire passing at a side face, which can well improve the above mentioned situation.

Referring to FIG. 20 to FIG. 26, the rearview mirror support having a screw for locking at a front face and a wire passing at a side face provided in the present embodiment comprises a support body 101, a fixing screw 102, and a ball head 103 which are connected, wherein the support body 101 comprises a first connecting portion 104, and the ball head 103 comprises a second connecting portion 105, wherein the first connecting portion 104 and the second connecting portion 105 are connected, the fixing screw 102 passes through the first connecting portion 104 and the second connecting portion 105 to be connected with the ball head 103; a side portion of the ball head 103 is provided with a wire passing-through hole 106 through this ball head 103.

Such rearview mirror support having a screw for locking at a front face and a wire passing at a side face can be called as a rearview mirror support or a support, for short.

The support body 101 and the ball head 103 are main structural parts of this rearview mirror support. The ball head 103 is used for connecting a rearview mirror body, the support body 101 is used to mount the rearview mirror onto the automobile, and the fixing screw 102 is used to connect the support body 101 and the ball head 103. In such rearview mirror support, detachable connection between the support body 101 and the ball head 103 is realized through the fixing screw 102, so that various parts are conveniently processed, it is also quite easy to assemble, and subsequent maintenance also saves time and effort.

The support body 101 and the ball head 103 are further connected through the first connecting portion 104 and the second connecting portion 105. In assembly, the first connecting portion 104 and the second connecting portion 105 are firstly connected, and then they are connected with the fixing screw 102. The configuration of connecting the first connecting portion 104 and the second connecting portion 105 makes it convenient to assemble the support body 101 and the ball head 103.

The side portion of the ball head 103 is provided with the wire passing-through hole 106. The wire passing-through hole 106 is used for allowing a wire 201 to pass therethrough, so that the rearview mirror can be conveniently connected with an electrical system of the automobile.

In such rearview mirror support, the support body 101 and the ball head 103 are connected through the fixing screw 102, the wire passing-through hole 106 is provided at a non-central position on the side portion of the ball head 103, and the fixing screw 102 is provided at a position of the ball head 103 relatively close to a middle portion. With such manner of arrangement, the whole rearview mirror support can be made relatively short and relatively small, so that it easily complies with relevant safety standard requirements, thus the rearview mirror glass cannot sway or shake easily after the rearview mirror body is connected.

Therefore, the structural design of such rearview mirror support having a screw for locking at a front face and a wire passing at a side face is reasonable, the size of the rearview mirror support is relatively short and small, facilitating assembly and utilization, so that phenomena such as shaking of the rearview mirror in use do not easily occur, the reliability of products is improved, and the failure rate is reduced, which is in favor of marketing.

Moreover, the screw is used for locking in the central position, and the wire passing-through hole 106 is formed at the side face of the ball head 103 for allowing the wire to pass therethrough, so that the wire inside the rearview mirror can more smoothly leave the rearview mirror. Thus, not only the support is connected and fixed, but also the wire extends out of the rearview mirror.

The connection between the first connecting portion 104 and the second connecting portion 105 facilitates connection of the support body 101 and the ball head 103, and also facilitates installation of the fixing screw 102. Optionally, the first connecting portion 104 has an outward-projecting structure, and the second connecting portion 105 has an inward-recessed structure.

It is relatively convenient to assemble the first connecting portion 104 and the second connecting portion 105 having such structures.

The first connecting portion 104 and the second connecting portion 105 have the projecting structure and the recessed structure respectively. Preferably, an outer profile of the first connecting portion 104 and an inner profile of the second connecting portion 105 are matched. With such configuration, the two portions achieve a higher degree of cooperation, and they are more stable after the connection.

In order to make the support body 101 and the ball head 103 not rotate relatively to each other after the first connecting portion 104 and the second connecting portion 105 are connected, the outer profile of the first connecting portion 104 has a polyhedron structure. The first connecting portion 104 and the second connecting portion 105 having such structures can serve a stop function, and after connection, the support body 101 and the ball head 103 will not rotate, facilitating utilization.

Preferably, the side face of the first connecting portion 104 is an oblique face. The structure of the oblique face facilitates assembly and has a higher fitting degree.

In some examples, the inner profile of the second connecting portion 105 and the outer profile of the first connecting portion 104 are matched, and the outer profile of the first connecting portion 104 is a square pyramid. As shown in the figures, the first connecting portion 104 and the second connecting portion 105 having such structures, on one hand, facilitate processing and assembly, and on the other hand, result in a relatively high fitting degree and a relatively good stop function after assembly, and can prevent relative rotation of the support body 101 and the ball head 103.

The fixing screw 102 is used to fix the support body 101 and the ball head 103. Specifically, the fixing screw 102 comprises a rod head 107 and a rod body 108 which are connected. The rod head 107 is located at the outside of the first connecting portion 104. As shown in the figures, various parts with such positional relationship facilitate assembly and maintenance.

More specifically, the ball head 103 is provided with a threaded hole 109. This threaded hole 109 communicates with the second connecting portion 105. An axis of the threaded hole 109 is overlapped with the axis of the ball head 103. Such positional features make more stable the connection between the support body 101 and the ball head 103.

Optionally, an axis of the wire passing-through hole 106 crosses an axis of the threaded hole 109. Such relationship makes the axis of the wire passing-through hole 106 tilted so that the wire 201 can conveniently pass therethrough.

The support is used to be connected with the automobile body, and can have various structures. For example, the support body 101 is in an L shape or an arc shape. As shown in FIG. 24 to FIG. 26, all of the supports with these structures can realize its function.
